For the second time, a purported iPhone 5 chassis has popped up in a video on the Web.

Japanese site Macotakara posted a video -- dubbed "iPhone 5 Housings?" -- from YouTube that shows a person holding what could be the next iPhone. The device appears to come with the long-rumored, taller 4-inch display, and a plate on the back that extends for part, but not all, of the device's backside.

In addition, the video shows the purported iPhone 5 with a smaller dock connector port as well as the headphone jack on the bottom.

The video is notable for showing what appears to be the same chassis found in a clip uploaded to YouTube last month. Like this chassis, the hardware in the previous video shows a unibody case that seems to confirm a host of rumors that have surfaced, including talk of Apple moving the headphone jack from the top of the device to the bottom and a smaller dock connector port.

That earlier video followed the publication of a host of photos showing what appeared to be the same device. With this latest video now out in the wild, it's possible the rumor mill might be closing in on the eventual design of Apple's next iPhone.

Then again, it might not. Apple has not, of course, confirmed that there is such a thing as the iPhone 5, let alone when the much-anticipated device might launch or what sort of features it'll have. And until the company confirms that the device exists, all videos, photos, and rumors should be taken with the proverbial grain of salt.

CNET has contacted Apple for comment on the video. We will update this story when we have more information.
